Size and stage composition of age class 0 Antarctic krill (Euphausia superba) in the ice-water interface layer during winter/early spring
Abstract: The condition and survival of Antarctic krill (Euphausia superba) strongly depends ... on sea ice during winter. How krill utilize sea ice depends on several factors such as region ... and developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains largely ... unknown. The aim of this study was to improve the understanding of the krill's interaction ...

Development of the krill stock in the elephant island region during the 1996/97 season
Abstract: During December 1996 the Elephant Island standard grid was surveyed for krill and salps ... . Krill and salps were present at almost all of the stations, other epipelagic zooplankton species were ... relatively scarce. Maximum krill density exceeded 7350 juvenile krill per 1000 m3. In general krill density ... was much higher than in previous years. The krill stock was dominated by length classes around 35 mm ...
